ABSTRACT:
In a bearing member of an internal combustion engine, having a flame sprayed surface, molybdenum or tungsten carbide is known as the material of the flame spray. The present invention aims to provide, for example a flame-sprayed piston ring with good heat-and-wear-resistance as well as a property of not seriously wearing the engine cylinder or cylinder liner. The flame sprayed layer of the present invention is composed of mainly ferrochrome powder and plus a powder of a self fluxing alloy, and additionally molybdenum. The piston ring of the present invention is suitable for heavy duty internal combustion engines, in which wear of the piston ring and cylinder are severe.
